UUID Class clockSequence() method

• clockSequence() method is available in java.util package.
• clockSequence() method is used to retrieve the clock sequence linked with this UUID.
• clockSequence() method is a non-static method, it is accessible with class object only and if we try to access the method with the class name then we will get an error.
• clockSequence() method may throw an exception at the time of the clocking sequence.

    public static void main(String[] args) {

        // Instantiate UUID    
        UUID uuid = UUID.fromString("46400000-8cc0-11bd-b43e-10d46e4ef14d");

        // is to return the clock sequence of this UUID
        System.out.println("uuid.clockSequence(): " + uuid.clockSequence());
    }
}

Output

uuid.clockSequence(): 13374
